Beats all the water types in RU 1 on 1, such as Crawdaunt, Feraligatr, Kabutops, and Lanturn, with ease thanks to its immunity to water type attackers and giga drain to restore health while attacking.

Walls Certain Physical attackers such as Cinccino, Archeops, and Drapion something its competitor tangrowth, cannot do, because it is weak to their stab attackers(bar cinccino)

Storm Drain gives cradily a much needed water immunity, allowing it be immune to the pesky scald burns. When targeted with a water attack, cradily gains a special attacks boost making it powerful enough to do some damage

Recover lets cradily repeatedly survive the onslaught of powerful attacks in RU, while simultaneously out stalling its opponents, unlike synthesis, it isn't affected by the presence of hail

Thanks to the new move tutors in BW2 cradily's ability Storm Drain, is now compatible with both stealth rock and giga drain giving it much more utility as a wall

Giga drain is the attack of choice which allows cradily to hit water and ground type hard while simultaneously recovering copious amounts of health

With Stealth rock being legal on a defensive pokemon, having it on cradily is almost mandatory so that it can support its team to the best possible degree.

Earth Power is nice move that is now legal with Storm Drain. With it, cradily is able to beat pokemon such as magneton, steelix, and drapion, pokemon who would have normally beat cradily

Hidden Power fire nails pokemon such as durant and escavalier pretty hard while doing damage to fellow grass-types lilligent and sceptile

Hidden Power rock is cradily's only option for a stab rock attack on the special side. With it, it can OHKO moltres after rocks while doing a ton of damage to flying types attempting to wall cradily.

Toxic when it is used in conjunction with recover and Hidden Power fire allows cradily to Toxic-stall its opponents, while Hidden Power fire targets the Steel-Types who are immune

[ADDITIONAL COMMENTS]

A physical attacking version of the Defensive set is plausible as cradily has equal offensive stats and an acceptable move pool in each of them to make good use of its attacks

Seed bomb is decent stab options that can replace giga drain. Seed bomb hits Ground and water types pretty hard and does more damage to slowking than giga drain.

Earthquake and Rock slide are acceptable alternatives to the final attacking slot hitting fire types pretty hard. Rock slide is better to hit flying types such as braviary, while earthquake targets steel types such as magneton.

If a physical attacking version of the defensive set is used, the nature should be calm, lowering the special attack stat instead of the physical attacking stat.

The special set, however is better to use as it is is not susceptible to attack drops from burns or intimidate, while also taking advantage of the special attack boost from storm drain.

Alternatively, cradily can run a mixed offensive wall set with a relaxed nature due to rock slide and earthquake having a much higher base power, however most threats cradily targets are hit much harder on the special and the boost from storm drain is often too good to pass up.

Cradily can replace Stealth rock with a coverage like Hidden Power Fire or Rock, allowing it hit a large array of pokemon for SE and be an excellent pivot for a larger array of pokemon

This set attempts for cradily to slowly start sweeping thanks to curse raising the defense of cradily while providing an attack boost

The EVs are dumped into special defense which allows cradily to survive a plethora of special attacks such as avoiding the 2HKO from nidoqueen's sludge wave

After a few boost cradily becomes incredibly difficult to take down, recover allows cradily to sustain longevity through out the match while continuously boosting

Seed bomb murders the water types that infest the tier, while also being an acceptable stab option

Rock slide works better with earthquake and lets cradily get past flying types such as moltres and braviary. Rock slide and earthquake give cradily the excellent edge/quake coverage

Suction cups prevents a phazer from forcing cradily out of the match allowing to it rack up boosts with out worry

[ADDITIONAL COMMENTS]

Cradily can run Stone Edge to replace Rock slide for the extra power boost. However, as a defensive booster, the extra PP and accuracy is much more appreciated

Storm Drain can be used to replace suction cups, giving cradily in immunity to water attacks. At the same time, cradily can use Ingrain in replacement of recover, allowing cradily to benefit from the water Immunity while also being insusceptible to phasing. However the combination of recover+suction cups is superior in most situations and requires less effort.

Bullet seed can be used over seed bomb as it has the ability to break through substitutes and can even be stronger than seed bomb if it 4 or 5 times. The consistent power provided by seed bomb generally makes it the better option.

Cradily can end up running a rest-talk set in place of recover and and a coverage move in order to function more as a status aborber, while also being able to stall out walls with toxic such as uxie and slowking

Hazard support along with the elimination of fighting types is much appreciated. This makes Uxie a wonderful partner as it can set up SR and blast away at the fighting types with psychic

Slowking, while not able to set up hazards, can defeat fighting type attackers while also dealing well with hail teams that cradily has trouble with

[Other Options]

Confuse ray and swagger are decent options which could potentially give cradily a free turn, but it is generally an inferior option with not too much utility

Stockpile, amnesia, and barrier are all decent defensive boosting moves, however cradily is better off boosting its attack and defense with curse

A swords dance set is also plausible but with all the new threats that can trouble cradily along with the resurgence of hail in ru, it generally isn't a good idea to attempt to sweep with something so vulnerable and slow

Mirror coat can be used for a surprise KO, but after the surprise factor fades away, it becomes useless and a waste of a move slot. Tickle is an alright option, this allows cradily to weaken fighting type switch ins and eases the job of its teammates.

Due to the omnipresence of hail, cradily can set up sandstorm to disrupt the opposing hail team while also gaining a meaty Special defense boost.

[Checks and Counters]

Fighting types are the number one way to combat cradily. Pokemon such as gallade and medicham can easily demolish cradily with either Close combat and Hi Jump kick, respectively.

Hail is also a good way to deal with cradily. The hail damage negates cradily's leftover recovery making it easier to take out. Hail abusers such as jynx and rotom-f can take cradily out with ease thanks to high powered stab blizzards

Durant and escavalier can both come in easily and set up on cradily and ko her with their respective stab attacks, however both have to be wary of Hidden Power Fire

Other bug types such as accelgor and Galvantula both threaten cradily with a powerful stab bug buzz, both have to watch out for an incoming rock slide or Hidden power

Amoongus deals well against cradily as it can remove the boost with clear smog and then cripple it by using spore and continually attacking it with giga drain

Fire types like moltres and magmortar can blast away at cradily, however moltres has to watch out for Rock Slide and its respective Hidden Power, while magmortar has to be wary of cradily's coverage moves.

Toxic is another good way to get rid of cradily. As a wall with no way to remove status, toxic severely limits cradily's longevity making it easier to take out through repeated attacks

in the curse set you should mention in AC Rest +Sleep Talk instead of Recover and Earthquake, you lost a bit in coverage (that isn't a big deal, since no one is immune to Rock Slide), but you can heal pesky statuses like Toxic.
